This is a replacement part that upgrades the String Jaw system on Klipper USA stringing machines made in 1992 or earlier. If your machine currently has the Old Style (2-piece) String Jaws you can increase the holding power and eliminate string slippage by upgrading to the New Style (3-piece) String Jaws. This conversion kit includes a set of New Style String Jaws, 2 New Style Shoulder Screws and a new Tension Arm for your machine.
